Kaiser
The frequency resolution when using the Kaiser
window is fair; the spectral leakage and amplitude
accuracy are both good.
The Kaiser window is best used when frequencies
are very close to the same value but have widely
differing amplitudes (the side lobe level and shape
factor are closest to the traditional Gaussian RBW).
This window is also good for random signals.
Bartlett
The Bartlett window is a slightly narrower variant
of the triangular window, with zero weight at both
ends.
Figure 4-1, Figure 4-2, Figure 4-3, Figure 4-4, Figure 4-5, Figure 4-6
are examples for
measuring sine wave with a frequency of 1kHz under the selection of six different
windows for FFT:
